With a new year brings trends that we're ready to welcome into the fold and others that can see themselves out. But which is which? Read on for insider info from the pros at Saks Fifth Avenue, Bloomingdale's, The Shoe Box, and other major retailers.

IN:"Stripes are the equivalent to what a white t-shirt used to be back in the day," says Roopal Patel, fashion director of Saks Fifth Avenue. "They have nine lives. We've seen the trend now for two to three seasons and it will continue to carry forward."

IN: "Sneakers will continue to be extremely popular in the upcoming year," advises Gennie Yi, Intermix's buyer of designer and ready-to-wear. "Because of their versatility, you can never have too many. Glitter, leopard, and satin updates to sneakers effortlessly dress up an outfit and give you a reason to buy multiple pairs."

IN: "One shoe trend we see really taking over in 2017 is the mule," says Sean Kirschenbaum co-owner of The Shoe Box. "Flat mules, low block-heel mules, heeled mules, sneaker mules, espadrille mules—mules in all fabrications and colors including velvet, satin, canvas, and embroidery. They were big for 2016 and they will be even bigger for 2017."

OUT: "There’s a fresher graphic interpretation of the sweet and romantic trends of 2016," says Yi. "The tulip flare has moved onto a sharper asymmetric hemline, the soft lingerie-dressing look has evolved into strong and powerful corsetry details, and the romantic and luxe velvets of the past are now modernized with an easy-to-wear attitude."

OUT: "A huge change is coming in the denim world," warns Jaffe. "Skinny jeans with stretch have reigned supreme for a long time but we anticipate a shift toward contrast denim styles in vintage silhouettes."

OUT: "Corsets had such a huge moment this year, but I’m not sure if I see designers continuing this into 2017 after the trend was covered in such a major way in the press," says Foley.

OUT: "Heels four to five inches or higher have been a trend that we have seen rapidly decrease," notes Kirschenbaum. "Women nowadays are way more focused on comfort and practicality (and value investing in a shoe that is both stylish and comfortable enough to walk or commute in) which is why there has been such an increase in demand for sneakers and low block-heels."

OUT: "I think we're starting to see that clean classic sneakers are not as exciting anymore," says Patel. "It's now about sneakers that are embellished or have something like emojis or logos on them."
